Brass channel guide



July 27, 1937. A. v. WEAVER BRASS CHANNEL GUIDE Filed Sept. 28, 1936 Patented July 27, 1937 UNITED STATES PATENT OFFICE 3 Claims. This invention relates to channel guides designed for use in connection with Venetian blinds, the primary object of the invention being to provide means to hold the slats of the blind against movement within the frame in which the blind is mounted.

An important object of the invention is to provide a channel guide of this character which may be embedded in the plaster of which the wall is constructed, with the result that the guide is entirely concealed in the plaster, the guide being so constructed that when the plaster shrinks away from the guide, during the setting of the plaster the usual unsightly opening or cracks formed along the guide incident to such shrinkage'are concealed by the curved flanges of the guide.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement' of parts and in the details of construction hereinafter described and claimed, it being embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a sectional view through a window frame and channel guide constructed in accordance with the invention, showing the plaster of the wall, completely concealing the channel guide.

' disposed in spaced relation.

Figure 2 is a perspectiveview of a channel guide, constructed in accordance with the invention.

Referring to the drawing in detail, the body portion of the guide is indicated generally by the reference characteri, and as shown, is of substantially channel formation, the edges of the body portion being extended inwardly towards each other, providing flanges 6, the edges of the flanges being curved outwardly and away from each other as at I.

This construction provides curved lips 8 that have their edges bevelled with the result that when the guide is positioned, and plastering material is positioned around the guide, the outer surface of the wall will be flush with the edges of the lips B, and portions of the plaster material will fill the space between the lips 8 and outer surfaces of the flanges 6, locking the channel bar against movement.

The body portion is pr, vided with openings,

I with each other, which openings accommodate the securing screws 9, which screws are embedded in theseunderstood that changes in the precise curing-strip iii, which may be a part of the window frame with which the channel bar or guide is used, or may be in the form of a strip secured to the frame of the window.

The reference character ii designates a slat of a Venetian blind, and the reference i2, designates a shank extending into the channel guide, the shank i2 being provided with a head i3 to prevent, the shank i2 from becoming displaced from the opening within the channel guide.

From the foregoing it will be seen that due to the construction of the curved lips, pockets are provided longitudinally of the channel guide, for the reception of the plaster which is positioned within the pockets, during the formation of the wall or window frame in which the channel guides :e used. It will therefore be seen that shrinkage of the plaster where the plaster contacts with the metal guide, is less noticeable than other types of guides wherein there are no pockets provided for the reception of the plaster material.

Having thus described the. invention, what is claimed is:

1. A channel guide for Venetian blinds, adapted to be embedded in the plastic material of .a wall construction, said guide comprising a member constructed of channel bar material, portions of the sides of the channel bar material extending inwardly toward each other providing flanges, and portions of the flanges being gradually curved outwardly and rearwardly, exposing the edges of the flanges at the face of the plastic surface of the wall construction.

2. A channel guide for Venetian blinds, adapted to be embedded in the plastic material of a wall construction, said guide embodying a length of channel bar material, lips formed along the longitudinal edges of the open side of the channel bar material, said lips being gradually curved outwardly and laterally, the outer edges ofthe lips being beveled to lie flush with the surface of the plastic material, exposing only the edges of the lips.

3. A channel guide for Venetian blinds, oomprising a body portion adapted to be-embedded in the plastic material of a wall construction, said body portion having an open side defining parallel side members, said side members bein gradually curved outwardly and laterally, and the free edges of the side members being beveled and adapted to lie flush with the surface of the plastic material of thewall construction, exposing the outer edges of the side members at the face of the plastic surface of the wall.
